OAM-PM Service Summary report

Overview

OAM-PM Service Summary reports show an aggregated view of session statistics on a specified service over a specified time period, grouped by service ID.

The report includes the following session types:

ETH-CFM Session
TWAMP-Light Session

The following service types are supported:

Epipe
VPLS
VPRN
MVPLS

Use cases

QoS analysis—Identify potential service impacting issues based on thresholds for latency, jitter and packet loss between specific NEs.

Troubleshooting—Troubleshoot service performance by service and segment

Prerequisites

The following tasks need to be performed using NSP Classic management for OAM-PM Service Summary reports to be created:

A DMM session must be defined with accounting enabled.
A TWAMP-Light session must be defined with accounting enabled.
For session loss information to be available, an SLM session must also be defined.

Report inputs

The following table shows the report inputs.

Table 13-22: OAM-PM Service Summary report inputs

Prompt	Notes
Session Type	ETH-CFM Session, TWAMP-Light Session
End Date	Calendar date or relative date (for example, two days ago) and time
Granularity	Aggregation types: None (raw collection interval) Hourly Daily Monthly
Report range	Length of time to be reported, in minutes (minutes, min), hours (hours, h), days (days, d), or months (months, m)
Service Type	Search using partial names or full names. A wildcard () will display all service IDs. Search service ID ranges using hyphens, for example, 1-200. Select individual items or click Select All*.
Service ID Range
Bin Type	Frame Delay—The Avg Delay, Min Delay, and Max Delay in the report output is the delay in microseconds Frame Delay Range—The Avg Delay, Min Delay, and Max Delay in the report output is the delay range in microseconds Inter Frame Delay Variation—The Avg Delay, Min Delay, and Max Delay in the report output is the delay variation (jitter) in microseconds
Result set limit	Number of results to report
Show report output on one page	Select the check box to enable pagination. Note: Using the Show report output on one page option when creating reports as drill-downs may impact report rendering time. Nokia recommends disabling the Show report output on one page option when creating reports.

Drill-down support	Yes—Opens an OAM-PM Service Site Summary report of the selected session type: an view of the results of tests on the service. From an OAM-PM Service Site Summary, open an OAM-PM Service Site report of the selected session type: an view of the results of tests on the site. From an OAM-PM Service Site report: Click on a delay result to show an OAM-PM Latency report. Click on a jitter or loss result to show an OAM-PM Loss report.
